Kim WK, Marcotte EM, Age-dependent evolution of the yeast protein interaction network suggests a limited role of gene duplication and divergence, PLoS Comput Biol, 4(11):e1000232 (2008) PubMedLinkPDF Supporting python code: network_growth_functions_fixed_module.py Note that this code used an older version of the igraph library (0.4.2); the latest version that we've tested (0.5.2) gives somewhat fewer large clusters than our published clusters due to changes in the function "G.community_fastgreedy()", possibly resulting from modifications to the handling of ties in the community merging process. The previous igraph library (0.4.2) is linked here: python-igraph-0.4.2.tar.gzigraph-0.4.2.tar.gzigraph_base.py
